According to the current clinical treatment and statistics, most patients with thyroid cancer can be self-cured by timely radical thyroidectomy and postoperative chemotherapy, which means the survival rate is very high, even over 90% or higher. Most of them are papillary carcinoma, follicular carcinoma, medullary carcinoma and undifferentiated carcinoma, most of them are papillary carcinoma, except undifferentiated carcinoma, which accounts for a very small percentage of the cases and is prone to blood or distant metastasis in the early stage and has a poor prognosis, including papillary carcinoma, follicular carcinoma and medullary carcinoma. After timely radical resection, the 5-year survival rate or survival rate can reach more than 90%, which means most patients can be cured.
